COIN-CONTROLLED LOCK AN D CON YEYER.

Specification of Letters Patent. Application filed February 28, 1911.

Patented Aug. 6, 1912. Serial No. 610,192.

To all whom it may concern:

Be it known that I, WILLIS S. FARNS- WORTH, citizen of the United States, residing at Petaluma, in the county of Sonoma and State of California, have invented new and useful Improvements in Coin-Controlled Locks and Conveyors, of which the following is a specification.

v This invention relates to coin controlled locks, and particularly pertains to a device for controlling It 18 the object of this invention to provide coin operated mechanism for controlling locks, b means of which the lock can be operated on y by the depositing of a proper coin or token.

A further object is controlled device which applied to the ordinary cylinder locks now in use, without altering the lock structure to any extent, and which is simple in construction, economical in manufacture, durable, not liable to get out of order and efiident in operation.

Another object is to provide means by which a series of so erposed locks may be operated separatel y separate coins and the coins conveyed 'througi a single chute to a common receptacle as is desirable in locker construction.

The invention consists of the parts and the construction and "combination of parts, as hereinafter more claimed, having reference to nying drawings in which Figure l is an elevational view of a portion of a locker cabinet showing the invention as applied. Fig. 2 1s a view in elevaremoved, illustrating the positions tron of the nearof the lock with the lock assumed by the parts in the first stage of their operation following the deposit of the coin. Fig. is a similar view showing the second position of the parts. Fig.4 isa detail View of a cylinder lock, depicting the 'manner in which the cylinder is blocked and revented from being operated. Fig. 5 1s a vertical section on the line X-X, Fig. 3. Fig. 6 is a horizontal section on the line YY. Fig. Fig. 7 is a detail view of a cylinder lock with parts broken away showmg the manner in which the key is blocked and prevented from being removed.

his invention is especially designed for i i l i I l I retains the lat-t use on the doors of lockers,

, time.

cabinets, closets advantageous to or for the rental oor. It is particulockers in hat and and the like, where it is collect toll for admission to of the space behind the d larly applicable to use on cloak rooms, laces Where a number of safe deposit boxes and the like are installed and where each separate door is provided with a special lock and key.,

This device is so designed that the key the operation of a lock by cannot be removed from its respective lock means of coins, slugs or other tokens.

unt1l a certain coin has been deposited, nor a lock locked or unlocked without the previous dropping ot' a coin, but when the re quired coin is deposited, the customer or user may look the desired door and remove the key for opening the door It is also so constructed that the locker can be used but once for a single coin.

In the drawings A represehts a door which may be hingedly mounted in any de sired manner in a frame B.

C is the barrel of a cylinder lock of any suitable type mounted in a cylinder casin D and having the usual loose pins 2, which are actuated by the insertion of a key 3 1n the keyhole 4- e'xtending longitudinally through the barrel C. A bit or projecting pin 5 is suitably attached to the inner end of the barrel C and is adapted to actuate snnilar bits 5 on a sleeve on the barrel, one of which bits 5 works in a recess in one side of a latch bolt 6, to advance and retract bolt within the lock casing 7 when the barrel C is rotated properly, as shown 111 Figs. 2 and 3. Thatlatch'bolt 6 is normally retained in its innermost position by spring 8, which bears against projecting upwardly from the rearwardl extended. portion of the latch bolt 6. This lever 9 projects through a slot in the casing an is loose on the pin 10. The inner end of the lever 9 is counterweight-ed so as to overbalance the outer end and er in its uppermost position, in whiclrpositiou a. notch 11 on the upper edge of the lever will be engaged by upper end of the slot in the casing 7 when the bolt 6 is in its retracted position. Vl 'hen normally at a future will now be described. Theloc'k, case 7,

carrying the cylindrical. casing'l); barre] U and the latch bolt 6; is mounted on'a 'plate 12 which is de'signed to be co nter'sunk'in the back of the vertical jamb member B;

and flush therewith. 'For-me'd'on thezirine'r face of the plate 12. to one side of the lock case 7 i'sapair" of verticaily' extending spaced ribs or flanges 13-43, whichpro-' ject outward against a= transparentplate 12 niountedin thejarnbB'to form aguide slot for a -coin:* A portion of the rib l3,

nearest thelock-case 7,1 is removed so that the outer endaofthe lever 9 will project therebeyond intothe path of acoin which may pass downward between the ribs 13-13", as shown in: Fig. '2. Pivotally i J Tint the leven'Sisnormally vertically disposed curved lever 14 on the upper end of which is formed a knob 15 which is adaptedtobeengaged by a notch 16 onthe underside of the outer end of the lever, as will presently bede'scribed;

The operation of the invention is 'as followszA-ssxime: that thepparts to be in the normal position shown %in Fig. 2 with the key 3 in the cylinder-v G, the door A open,v

and the latch 6 retracted; In this position it will bet seen that :the door A cannot be locked in the closedpcsition by reason of'the notch 11 in the lever 9 being engaged by the casing 7, wl1-ichprevents the'nccessary turning of the cylinder ll to throw the latch bolt 6. Neither can. the key 3 be withdrawn from the cylinder 1C by reason of the latter being slightly turned to one side when the lever 9 is in engagement. In this-position the loose pins 2 are not in alinement with the pins (not showny in the cylinder I), but

bearagainst'the walls inside the cylinder, as shown inFig. 7, thus blocking the key 3 against removal. It is understood that with locks of Yale type a key can only be withdrawn when the keyhole and hey stand in a certain position, usually vertical. It being desiredvtojlock the door A and remove the key 5), a. coin of the proper value, for instance, a five cent piece, is inserted in a slot 17 formed in. the casing B, and which communicates with the guide slot on the plate 12, through an inclined chute 18. This coin; traveling down inclined chute 18 drops blocks the lock untilanotherl upon the trap-lever depress the outer end of the latter as shown in Fig. 2, thus releasing the notch -11 from the casing 7,

of the coin and cause'sfits entire Weight to rest on the outer end of the lever 9 to main:

tain it in its lowerm'ostposition', In this position the lock end of the lever 9'is dropped sufficiently td disengage "the notch 11 from the casing 7 5 thus permitting the barrel C to be rotatedby'the l tey'3 in'th e direction of the arrow; Fig: 4, so as to throw the latch 6 out of the easing? into engage ment with a keeper on the door A previously closed, and" thus prevent its beingflopeneda On turning the barrel 0 as'just' described,

the swinging lever 9 is drawn forward by" the pin 10 on the bolt 6, so thatthe coin 19' will drop between the end of the lever '9 and the flange '13 upon the semi crescent" g shaped lower end of the lever 14 which has been previously disposed across the'chute'by the forward movement of the lever 9, where it comes to rest, andis sustained as shown in Fig. 3. 'The doorA being now closed and locked, and the barrel C revolved so as to 'throw the keyhole into avertical' position, permits of the 'renioval'o'f the key 3, as is well knownin cylinderlock construction. When it is-desired to unlockthe I door A the key 3 inserted in the barrel "C in-the usual-manner, and the barrel returned to its nomad-position. As the-barrel C is rotated the bolt 6 is retracted so as to per'r mit [the door to swing outward; the lever 9 being engaged with the bolt 6 returning to As the lever 9 moves backward,

normal. I the lever 13- is rocked on its pivot so as'to release the coin l9 and permit 'it'to drop" downward into -a chute 20 which is formed by mounting a verticallydisposed channel mold 26 on the back of the casing as shown in Fig. 5.' Themomont the coin'is released, the lever 9 is'rocked omits-pivot" I to release the knob 15; from the 'notch 16 ,andc'ause the/notch .llito' returnvinto ene' gagement with the casing 7 which again coin: is+deposited in theslot 17.." Q

Means are provided for adaptiii'g the do vice for use with coins of various 'siz'es' and ClQIlOHlil'liit'lOIlS; This is a'cc'omphshed adj ustably mounting abar on? the 1 plate 12, adjacent-the flange-JQQ- l-hiQbaT 21"1s disposed parallel withthe flange- '13 and 'is. designed to'be placed at-severalpoints remote therefrom 1n order 1to"regula'te the width of the coin passage. l or instance when the barQl is placed, IIICOHCHCt withthe flange 13, a five centpiece will inrpass mg .thrmighL-gthe coin passage, drop upionj and actuate the lever 0, while a one cent piece or a dime would pass on down the slot memos without affecting the lever. By setting the bar 21 away from the flan e 13' the coin passage will be narrowed to t either a dime or a penny so that the lever 9 will be operated-thereby. As a means of gaging the position of the bar 21 a series of notches-22 are formed on its up r end which are adapted to en ge the filiii e 13', each notch representing e distance t e bar should be spaced from.the flange 13 for-the several sized coins. This bar 22 is held in'place in its various positions by means of a clamp screw 24 which is threaded into the bar and extends through a slot 25 in the plate 12.

An important feature of this invention lies in the arrangement of the plate 12 and I the lock mechanism thereon, in the jamb B. This becomes apparent when a series of superposed doors A are employed; as in a locker cabinet, where if the lockis placed on the door it is obviously neceslij'to employ separate coin receptacles in rich door, or provide more or less complicated means for delivering the coin from the 6,0 "to a chute. In the arrangement here disclosed these difficulties are obviated by the use of the vertically disposed channel mold 26 which ma be made of either wood or metal on the bach of the jamb B, into which the coins are dropped from the lever 14; the coins entering the channel mold 26 under the lower edge of the plate 12. This mold 26 may be of any desired length and may lead to any suitable receptacle at its lower end.- It will be observed that the coin 19 will be sustained on the curved lever 14 during the time the door Ais closed and so that by perforating the casing B atfi, opposite the position occupied by the coin, the use of any but the required token can be detected. From the foregoing it will be seen that I have provided a means by which a door may be locked only by the depositing of a certain coin, which is particularly adapted for use on lockers, safe deposit boxes and the like. In this instance, the door A is swung to normally stand in an open position,iand the bolt in the lock in the casing B being rea tracted and prevented from bei advanced until the lever 9 is released by 'the proper coin, the locker space cannot be utilized and locked against access by the unauthorized persons until such coin'is deposited. This being done, articles may be placed within the locker and the door closed and locked and the key removed. The use of spurious coins, slugs, or other tokens than those de sired, is avoided, by reason of their being "retained on the lever 14 in line with. the perforation 27 during the time the door A is out of the closed and locked'in plain view of the attendant; this coin dro ping to a suitable till through the channe 26 when the door A is again unlocked.

Having thus described my invention, what I claim and desire to secure by Letters Patent is- I 1. In a lock having a coin chute and a lever extending in the chute to be recited by the weight of a coin,'of for adjusting the coin chute to receive diflerent sized coins, consisting of a vertically disposed bar, a clamp screw for retaining the bar in place, ste ped up notches formed on the upper end 0 the bar, and a rigid member en ageable by any one of the notches to gage t e position of said bar in relation to said lever. a a 2. In a-coin-controlled lock, the combination with a coin chute, of a normally retracted latch bolt, key means for reciprocatin the bolt, a dog mounted on and movable with the bolt and normall holding the bolt against movement and aving a portion which projects normally into the path of,85 the coin, and a detent normally out of the path of the coin controlled by the dog.

3. In a coin-controlled lock, the combination with a coin chute, of a normally retracted latch bolt, key means for reciprocat ing the bolt, a dog mounted on and movable with the bolt and normally holding the bolt against movement and having a portion which projects normally in'to the path of the coin, and'a detent separate from, but on 95 gaged by the dog and held thereby normally path of the coin controlied by said dog. i

4. In a coin-controlled lock, the combina' tion with a coin chute, of a normally relee tracted latch bolt, key means for reciprocating the bolt, a detent normally out of the path of the coin, a dog mounted on and movable with the bolt and normally holding said bolt against movement and having a portion which projects normally into the path of the coin, said detentbeing loosely connected to said dog and controlled thereby and adapted to be thrown into the path of the coin when the bolt is thrown forward to support the coin, said detent being again thrown out of the path of the coin when said bolt is retracted,

In testimony whereof I havehereunto set o my hand in the presence of two subscribing witnesses. 1
